This invention relates to valves and par? ticularly to mixing valves to which hot and cold water are led by'separate inlet pipes to become mingled in the valve casing and dischargedtherefrom through an outlet pipe to the place of use. Mixing valves as heretofore constructed have, asfar as lam aware, been addition to the mixing valve. such additional valves not only detracts from limited to the use ofa single discharge pipe and also'have not been provided with any means for regulating or controlling the vol-' ume of water deliveredthrough the discharge outlet. As aresult,'whenever it was desired to provide a plumbing installation consisting f of a bath tub and shower combined, it was necessary to employ separate valves for each part of the installation. If a volume control vwas desired, an additional valve in a sepa} rate housing has always been employed in the appearance of the installation, and 'nec-,

essarily increases the number of pipe joints and therefore the liability of leakage through such joints but'also produces aninstallation more diflicult and cumbersome to operate and regulate.

The principal object of this invention is to provide anew and improved construction for a mixing valve, in which means are provided for both temperature and volume'control, and in which two or inore separate outlets are provided, each having a separate manually operable shut-E.

I

Asshown in the'drawings, the valve comprisesa main housing 10, (see Fig. 4) having formed integral therewith the threaded inlets 11 and 12." Each ofthe inlets l1 and 12 has its outer endmachined, asindicated at 13, to provide alj oint for co-operation with a union nipple lt, the joint 13 being ground in the usual manner,-andthe union nipple being adapted to base-cured in position by means of a nut 15, which engages withth'e outer threaded portion of the inlet.

Projecting from the sides of the housing and integral therewith, is a pair of outlets 16, 17, said outlets as shown preferably ex tending at right angles to the inlets 12, 13. The interior of the outlets 16, 17are screwthreaded for the attachment of pipes or con duits which lead thewater to the place of use. The'valve housing 1G is also provided with an upwardly extending annular flange 18, which is threaded onboth its outerand inner surfaces for a purpose presently to be more fully described. into the interior of the housinglOand in axial alignment with the outlets 16, 17, (see Projecting inwardly I Fig. 5) are a pair of bosses 19, 20, formed 3 integral with the valve housing, Each. of the bosses 19, 20 is provided with a'bore 21, r the inner end of which isclosed by'a wall 22. y

The upper side of each of said bosses is pro vided with an aperture 23, whlch communicates with the interior of the valve housing,

and the openingofwhich is controlled by a valve plug presentlyto be described.

Seated within the housing 10 is a valve carrying cage 25, said cage'being provided at its upper end with a horizontally extending annular flange 26, which is seated within a counter-bore 27iof the housing. 10; The cage is provided, as shown in Fig. 4, with a pair of laterally projecting'apertured bosses 28 which form guideways for the valve plug holders 29, the latter being slidahly mounted Within the apertures of the bosses 28. Each of the holders 29 is bored out on one side to provide a cylindrical recess fora valve plug 30, the latter preferably being constructed of any suitable resilient material, such as rubber, and having the form of a hollow sleeve, the outer end of which reduced to form asmall projecting teat 31, which is adapted to enter into the bore of the respective inlet 11 or 12, which the plug intended to control.

Each plug holder 29 is provided on its other side with a small vertically extending semi-cylindrical recess, in which a roller 32 is adapted to be rotatably received. Each roller 32 has its upper end reduced, as at 33, and has rotatably mounted thereon a second small roller- 34, which is adapted to engage within a diametrically extending slot 35, provided in the annular flange 26 of the cage 25. Mounted upon the upper face ofthe cage 25'is a washer 36, the outer edge of which is seated within a second counterhore 37 of the valve housing 10 and the Washer and cage are held in position within the housing by means of screws 38 Fig. 2) which pass into suitable threaded lugs not shown) formed in the inner walls of the valve housing 10. v

Rotatably mounted in an aperture 31), formed in the lower wall of the cage 25, is a valve rod or shift 40, the upper end of which extends at a right angle and terminates in a ball-shaped handle 41. passes through a centralapertulc in a valve bonnet 42, the latter being provided between its ends with a laterally projecting annular flange 43. The bonnet 42 is held in place by means of a bonnet nut 44, rotatably mounted upon said bonnet and having a flange which engages the laterally extending flange 43 of the bonnet. The nut 44 scnews upon the exterior thread of the threaded flange 18 of the housing 10 and serves to clamp the honnet in position upon the housing with the lower face of said bonnet in tight contact engageinent with the washer 3G. The lower face of the bonnet 42 is counterboied as at 46 to receive a sleeve-like gasket 47 which encircles the valve rod 40. As clearly shown in 4, the gasket47 is of slightly smaller diameter than the counterbore 46 for a purpose hereinafterto be more fully set forth.

Secured to the valve rod 40 is a cam 48, havinga pair of diametrically opposite cam throws .49, 50, (see Fig. 2), which are adapted to engage with the rollers- 32 of the valve plug holders 29 when the handle 41. is thrown to the position shown in the drawings, thereby moving the valve plug holders with the valve plugs 30-incunted therein. outwardly of the cage 25, and forcing the ends of the plugs 30 into tight contacting engagement withthe valveseats provided, at the inner end of the inlets 11 and 12. The cam 48 is The valve rod 40,

also provided with a downwardly extending lug51, the side edges of which are adapted to engage with a stop screw 52 (see Fig. 5) for limiting the throw of the valve rod 40 and handle 41.

Mounted within a pair of screw-threaded bores. 53 (see Fig. 5) of the valve bonnet 42 are the lower enlarged screw-threaded ends 54 of the volume control valve rods 55. Each of said valve rods has its lower end reduced and threaded as at 56. Mounted upon the threaded lower end of each valve rod 55 is a valve plug 57, the lower end of which is cham fered and adapted to engage with the upper edge of the aperture 23, provided in the boss 19 of the valve housing 10.

In order to secure a full opening of the valve plugs57 with a relatively small movement of the rods 55 the threads upon the reduced portion 56 of said rods are of opposite pitch to the threads upon the enlarged portions 54, and each valve plug is provided with a pair of laterally projecting wings 57* which engage between the walls of an arcuate slot 57* (see Fi 3) for preventing rotation of the valve p ug when the valve rod 55 is 1'0- tated, whereby there will be secured a differential movement of the valve plugs for a given amount of rotation of the rods 55. The valve rods 55 extend through suitable aper tures provided in the upper wall ofsaid bonnet 42, and secured to the outer end of each rod, as by means of the screw 58, is an arcshapfd valve control lever 59. A suitable pac 'ng is provided for each valve rod 55, which packing preferably consists of a hollow sleeve 60, seated within a counterborc provided in the interior of the valve bonnet. In order that one of the valve rods 55 and parts associated therewith may be dispensed with if it is desired to use the valve for supplying a single fixture only, the apertures in the top of the bonnet 42 through which thevalverods 55 pass, are interiorlythreaded, as indicated by the reference character 61,"to enable a stop plug to be inserted therein to close such aperture. The valve bonnet 42 has drilled therein a pair of diametrically opposite holes or recesses 62 which are adapted to engage over the heads of the screws 38, the engagement of said holes with the heads of said screws serving to position properly the bonnet upon the housing, the heads of such screws functioning as dowel pins.

The operation of the valve is as follows: WVith the handle 41 in the position shown in the drawings, both of the intakes 11 and 12 are fully closed by the valve plugs 30. Movement of the handle in the direction of the arrowin Fig. 1 will cause the cam throw 49, Which,it will be noted, is shorter in length than the cam throw 50. to move out of contact with the roller 32 shown at the right hand side of Fig. 4. The pressure of the water against the valve plug will cause the roller to be held against the periphery of the cam and thereby, as theithrow' 49 moves out of contact 'withfthe roller 32, thevalve plug will move to its opened position, thus permitting the water to flow into the interior of the valve housing from the'intake 11 towhich the cold water supply is connected. 50 are so proportioned that the throw 50 will remain .in engagement with the roller 32, shown at the left hand side of Fig. 4, to hold the valve plug 30 at said side in closed position after the plug 30 at the right hand side has been opened; Consequently cold water only willrbe admitted intothe valve housing until the handle d1 has been moved sufficiently in the direction indicated by the arrow to bring the camthrow 5O outof con- V tact with itsres'pectiveroller 32. A further movement otthe handle will permit the valve plug at the left hand side to open under the pressure of the water, thus permitting the hot, water-to enter through the intake 12 I and mingle with the cold water admitted through the intake 11. The full opening of both valvesis securedwhen the handle l1 is snbstantial i gin a vertical position, that is to sa a osition a roximatelv 90 from c theposition'shownin the drawings. 7 Further movement of the handle ll Wlll bring the ,iorward end of the cam throw in engagement with theroller 82 at the right hand side of the drawings, thereby to close the cold water supply while leaving the hot water supply open. -The forward end of the cam throw 50 is so out that a gradualolosing of the cold watersupply valve may be secured, thus enabling the mixture of hotv and cold water to be determined as desired;

by changes in the position v0i the handle l1.

' If the valve is included as a part of an installation which includes two fixtures tobe supplied with water as, for example, abath tuband a'shower, the supply ofwater may be directed to either one of the fixtures, while the other is shut 05, or to both of them if so desired, by manipulating the control valve levers 59. The levers 59 are shownin Fig. 1

a c the supplyof water through the outlet 16 shown at the upper end of Fig. 1, which, it may' be assumed has connected I thereto a of the drawings in the closed position. Assuming for example that it is desired to direct shower fixture,-the lever 59 is thrown from the. full line. position to the dotted line position shown :lI1 Flg.'1, thereby causing the valve rod 55.to be rotated, andthe differential I screw thread arrangement causing thevalve plug 57.130 bemoved to its full opened position. If it is desired to direct the water through the outlet 17 shown atthe'bottom of Fig. 1,

the lever 59 shown in the lower part of said figure will be thrownin a similar manner to openihe other valve plug 57 Ifit isdesired to throttle the supply ofiwaterdelivered The length of the cam throws 49,

through either of the "openings 16 or 17 the" handles 59 can be setto a position intermediate the full line and the dotted line positions, thereby shutting ofi the valve to. any

desired extent, according to the, position of the lever. As will be seen fromtheforegoin and from an inspection of the drawings,

each of the valve levers 59 is, entirely independent of the other, so that either valve plug 57 may be entirely closed, While the other? valve plug 57 is open.

The small rollers 34 which are associated c with the rollers 32 co-operate with the, slots 35 provided in the annular flange of the cage 25 to keep the axis of the rollers'32 parallel ing. For example, the mixing valve rod 40 is journaled inv two removable members,

namely, the bonnet 42 and the cage 25 the;

flow control valves 57 and the parts connected therewith are alsomounted in the bonnet Y 42 and are removable with the bonnet so that. the operation of renewing one of the valve plugs 57 is averysimple one; the valve plug holders 29 areslidably mounted in the guideways forming in the laterally projecting boss-' es of the cage 25 and the bores provided in the housing 10 into which the valve plug holders 29, pass'a're larger in diameter than the plug holders, so that there is no contact between the plug holders and the valve housing. The operation of renewing the valve plugs 30 is a very'simple one, as all that is, required is to unscrew the valve bonnet nut 44 and remove,

the bonnet and valve rod 40. The valve plug holder can then be removed by pressing against the roller 34 and sliding the valve plug holder29 with the valve plug 30 contained therein towards the center of the valve housing until the holder ismoved clearofthe guideway formed in the boss 28, after which the valve plug assembly, comprising the rollers 32, the valve plug'and the valve plug holdeigcan be removed out through the open top of the valve. If, after extendeduse, the

cam 48 should become badly worn, it may be removed and a new cam substituted, by looseningthe screw -48 which holds the cam in position upon the mixing valve rod 40.

As it' may, bedesir'ed to use the mixing valve in many installationswhere a shower only ora tubonly is provided, I'have, for the purpose of standardizing the. manufacture, 1"

so constructed the valve thatit may beused I as a part of a double installation, with a pair of controls, onefor each fixture, as. annitary assembly havinga mixing valveand a single flow control, or asa uniting assembly having a mixin valve with the ow control eliminated. n thelatter case, the valve bonnet 42 and bonnet nut are not employed, but I substitute therefora plain bonnet 42 having a threaded flange at its lower end for engagement with the interior threads of the flange 18 of the valve housing 10. The bonnet 42 is provided with a laterally extending flange 42" which'extends over and covers the outer end of the flange 18.

In order to protect the exterior threads of the flange 18 and to give a neat finished appearance to the valve when used as a plain mixing valve, a bonnet cover cap is provided, which fits over the bonnet 42-. The cover cap 65 is furnished with a small projecting tab or car 66 apertured to permit the passage ofa fillister screw 67, the ear being counterbored to receive the screw head. The threads of the fillister screw are engaged with a screw-threaded hole 68 provided in I the outlet 17.

As a safeguard'against the shearing off of the stop pin 52 111 case excessive pressure I should be exerted upon the valve operating handle 41, the bonnet 42 is preferably provided with an upwardly projecting'flange or rib70 located adjacent to the valve rod 40. The latter is provided with a laterally projecting lug 71 adapted to co-operate with the ends of the rib to check the rotation of the valve rod and handle when the latter is swung to its extreme open or closed position.

It will be understood that the construction al details of the specific embodiment select lected for exemplifying the principles of the invention are merely illustrative and that many changes, variations and modifications of such details may be resorted to without de hiding from such principles. claim: 7
